Answer:
see below
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We can find the radius from the diameter
r = d/2 = 34/2 = 17
V = (3.14) (17)^2 * 27
V =24501.42 m^3
The surface of a cone is found by
SA = pi r^2 + pi r l where l is the slant height
We can find the radius from the diameter
r = 8/2 = 4
SA =(3.14) * 4^2 + 3.14 * 4*7
=50.24+87.92
138.16 in^2
The lateral surface area of a pyramid is found by taking the area of the sides
LSA = 4 * the area of a triangle
we multiply by 4 since there are 4 sides
= 4 * 1/2 b*h where b is the base of the triangle and h is the height of the triangle. (in this case it would be the slant height)
= 2 * 8 *22
=352 m^2
Answer:
1) 24501.42 m³
2) 138.16 in²
3) 352 m²
Step-by-step explanation:
1) Cylinder
volume = pi × r² × h
Radius = 34/2 = 17
Volume = 3.14 × 17² × 27
= 24501.42 m³
2) Cone
r = 8/2 = 4 in
(pi × r × l) + (pi × r²)
pi × r × (l + r)
3.14 × 4 × (7 + 4)
= 138.16 in²
3) Square based pyramid
4 triangles
4 × ½ × 8 × 22 = 352
